My son has a murmur which was picked up by the GP when he was about 7 months old. Drs can't hear it with a stethoscope at birth, they have to be older to hear it. After a cardiac ultrasound, we found out that he has an atrial septal defect. He will need an operation to close the hole in his heart when he is about 2. Apparently a lot of people don't know they have this murmer until they are adults. It doesn't cause symptoms until you are about 45 years old. As it is large enough to cause problems later in life, it will need an operation, and I will be glad when it's over. What scares me, is that the Dr said it will be day surgery! They just go up through an artery in the leg, to plug up the hole, and once the tissue grows over the plug, it will be like he never had a problem. Still, I wish he would stay in hospital overnight, just in case.

Missy good luck. From what I hear, most murmers fix themselves.
